Remove all tab/space mismatches from the Core project. For anyone working on a branch that heavily involves the core, I am so sorry.

- Also killed off some trailing spaces/tabs.

- Updated the license header to be consistent with the rest of the project (All projects are now done moving over to this)

- Also, killed some dangling else's (where appropriate)

Now all the tab fixing is done. No more of this crap should be needed to be pushed. Rejoice!
